Rainwater is the living element of fresh water cycle.

Rainwater assembled by the bioconcrete panels attached to the roof structure gathered into the cistern through the gutters and pipes.

Gathered rainwater being run to a “grey-water tank” at the early stage of raining due to dirt subsidence on the roof and in the air.

Special automatic device based on refraction to switch ventil when reaching limit so as to gather clear rainwater in the cisterns


BioBeton Cystern Technology

Mechanical particles – later to be removed through cleaning inlets- floating in the water settling to the bottom of the bioconcrete cisterns whilst the settling of the rainwater (24-36h)

Cisterns taking their beneficial effect on the raw rainwater by adjusting pH (from 7,0 to 7,5 ) by extracting carbonic H2CO3 while the built-in silver plate prevents the algae and bacterial pollution

RainWater Filter System


- utilities are not controlled
- chemical treatment
- high chlorine content
- high drug residues content


/ natural reactions the bioconcrete technology generates

- it filters out the CO2
- orientates and sets the pH to ideal range of 7.0-7.6
- further softens the otherwise naturally soft rainwater
- reduces the chemicals that can be dissolved into the raw rainwater from the "Particulate matter"( also known as particle pollution or PM).
- only natural processing: physical filtration, no chemicals
- only natural materials in the process based on bioconcrete material and process that acts like a natural limestone cave formation (no plastics at all in the process)

About the process

The complex rainwater management system is based on IVANKA’s material innovation, bio-concrete which has a pH neutral orientation and bio-compatible influence on the water. Both the technical specification of this material and the process itself distinguishes this new system from the traditional ways of rainwater collection. The specific technology allows filtering raw rain only physically in a strictly natural way without chemicals so the equipment can produce the highest quality, sun-distilled drinking water.

The technology’s testing is taking place in the location of IVANKA’s owners at Balaton Uplands National Park where geographic parameters are the most suitable for the project in Central-Europe. Lake Balaton is the largest freshwater-surface of Europe so the air is especially pure and rainfalls are favorably frequent in that region.

Why rainwater?

As Katalin and Andras Ivanka comment, ‘Because of the global population growth more and more freshwater is needed on Earth. Freshwater is an indispensable material of life but unfortunately nowadays it is becoming more and more difficult to get. In the near future priority of human needs will be inverted and among others, freshwater will be appreciated. It will be more important than oil or precious metals. Rain is the initial, the most important and purest, renewable source of the freshwater cycle – a much better choice than any other source such as lakes, rivers or mineral waters from underground. The technology we are working on represents a high ethical value as it turns rain into the highest quality drinking water in a pure and natural way of processing. It will provide access to affordable clean water for small and big scale users, from families to big companies, leaving the smallest possible ecological footprint in the process’.

human body is 65% of water
– we need 2 liters per day

7 billion people on earth
– 14 billion liters of drinking water every day

914 trillions of liter falls every day
– 65 thousand times that we need

We already use sun energy in our homes and industries – but we still let the purest, renewable source of water fall on the ground and meet pollution and dirt.

Rainwater is the living – most dynamic – element of freshwater cycle. The biological value, oxygen contents, and initial energy level of the Sun distilled rainwater are high. In the course of the natural cycle of the freshwater reserves, the water is the purest when falling from the skies. IVANKA concrete technology and rainwater management system preserves the highest quality of water. Ergo provide access to all families, industries, etc. with a rooftop, the highest quality water as a raw material.

IVANKA concrete structure and surface technically works out as a “water cave” formation for rainwater collection and storage. The main unique features of the tank are the following: its gentle, bio-compatible influence on the water, pH neutral orientation, location-based applications and the high sustainability index. The white cement based IVANKA BIOBETON CISTERN with the rainwater management technology are the main products of the sustainable water resource management.

The Water of Life project

A revolutionary system made of concrete turns rain into the highest quality drinking water. A new global perspective in sustainable development.

Milan Design Week 2014

At Milan Design week IVANKA, the leading designer concrete brand presented The Water of Life: a revolutionary project developed to collect rain and turn it into the highest quality drinking water filtered through a special bio-concrete system. A real innovation opening to global perspective that markedly transcends the current practice of sustainable development.

To reduce the CO footprint 80% by 2050 the new households must start using drinking rain technology beside grey water rain collection and sunpower.
